CHARLES XV. HAIGHT, OF MOUNT VERNON, NEW YORK.

DEVICE F ORSETTING SAWS.

SPECIFICATION forming part of Letters Patent No. 599,984, dated March 1, 1898.

Application filed July 13, 1897.

To all whom it may concern:

Be it known that I, CHARLES V. HAIGHT, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Devices for Setting Saws, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to devices for setting saws; and the object thereof is to provide an improved device of this class which is simple in construction and operation andwhich is adapted to be used in connection with any kind or class of saws. i

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a plan view of my improved sawsetting device, and Fig. 2 a side View thereof.

In the drawings forming part of this specification the separate parts of my improvement are designated by the same numerals of reference in each of the views, and in the practice of my invention I provide a triangular frame which consists of two inclined sides 5, which connect at one end to form a point 6 and which are connected at their opposite ends by a cross-bar 7, which is provided centrally'with a cross-head 8, which is provided with an outwardly-directed prong 9, which is shown in dotted lines, and by means of which a handle 10 is secured thereto. It will be understood, however, that the handle 10 may be connected with the cross-head 8 of the bar 7 in any desired manner, and said cross-head 8 is provided near its inner end with a perforation and centrally thereof or near the outer end with a corresponding perforation, through which is passed a setscrew or bolt 11, which is provided with a cross-head or handle 12, and the set-screw or bolt passes through a longitudinal slot 13, formed in a'bar 14, which is provided with a head 15, the under side of which is wedgeshaped in form, as shown at 16, and adapted to enter triangular transverse slots or grooves 17, formed in the upper surfaces of the sides 5 of the triangular frame. The slots 17 are preferably formed on both of the sides 5 of the triangular frame, but

Serial No. 644,400. (No model.)

I need be formed only on one side, if desired,

and these slots are arranged at a slight angle to the central longitudinal line of the crosshead 8, and the angle of said slots with reference'to said line increases as said slots approach the cross-bar 7 Mounted at each side of the triangular frame and adjacent to the cross-bar 7 are standards 18, which are provided with a plurality of transverse perforations 19, and each of said standards is provided with a shaft 20, on which a roller 21 is mounted, and these rollers project outwardly over the sides 5 of the triangular frame, and the bar 14, provided with the head 15, is free to swing on its pivotal support, so that the edge 16 on the bot tom of the head 15 thereof may enter either of the slots or grooves 17.

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.

In practice the saw the teeth of which are to be set is mounted in a vise, clamp, or other suitable holder with the teeth thereof 'directed upwardly, and the triangular frame of the teeth-setting device is held by the handle 10,

so that one side thereof will press on one sidev of the saw adjacent to the teeth and the corresponding roller 21 will slide over said teeth or rest thereon. The triangular frame is then moved along the side of the saw, the bar 14 having first been properly set, the angle of said bar always depending on the size of the teeth of the saw or the character thereof, and as the teeth-setter is moved along the side of the saw the head 15 of the bar 14: is depressed between the teeth of the saw by giving said head a slight blow with a hammer or similardevice, and the teeth are thus properly set. It will be apparent that the triangular frame .of the teeth-setter may be moved along both sides of the saw in this manner and all the teeth may be thus properly set.

It will also be apparent that the triangular frame may be of other construction than that herein described, and the cross-head 8 may extend the full length thereof, if desired, and

it will also be apparent that thecross-bar 7 constitutes the base of the frame and that the handle 10 is connected with said frame longitudinally thereof and centrally of said base,

and the object of forming the separate perforations through which the bolt 11 may be passed is to provide means for longitudinally adjusting the bar 14 or for changing the 1011- gitudinal location of the bolt 11, on which said bar is mounted.

My improvement is simple in construction and operation and perfectly adapted to accomplish the result for which it is intended, and it will be apparent that changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. A device for setting the teeth of a saw, said device consisting of a triangular frame, one of the inclined sides of which is provided with transverse slots or grooves which are formed therein at an angle to the l0ngitudinal center of the frame, and the base of said frame being also provided with a handle, and with a pivoted bar which is provided with a head the bottom of which is wedge-shaped in form and adapted to enter said slots or grooves, substantially as shown and described.

2. A device for setting the teeth of a saw, said device consisting of a triangular frame, one of the inclined sides of which is provided with transverse slots or grooves which are formed therein at an angle to the longitudinal center of the frame, and the base of said frame being also provided with a handle, and with a pivoted bar which is provided with a head the bottom of which is wedge-shaped in form and adapted to enter said slots or grooves, said pivoted bar being longitudinally adjustable on the base of the frame, substantially as shown and described.

3. A device for setting the teeth of a saw, said device consisting of a triangular frame, one of the inclined sides of which is provided with transverse slots or grooves which are formed therein at an angle to the longitudinal center of the frame, and the base of said frame being also provided with a handle, and with a pivoted bar which is provided with a head the bottom of which is wedge-shaped in form and adapted to enter said slots or grooves, said pivoted bar being longitudinally adjustable on the base of the frame, and said frame being provided adjacent to the base thereof, with a roller which is mounted thereon, substantially as shown and described.

4. A device for setting the teeth of a saw, said device consisting of a triangular frame one of the inclined sides of which is provided with transverse slots or grooves which are formed at an angle to the longitudinal center of the frame, and said frame being also provided with a pivoted bar the under side of which is wedge-shaped in form, and adapted to enter said slots or grooves, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 10th day of July, 1897.

CHARLES \V. IIAIGIIT.
